Please help with winter camp Number theory p19-21
not sure about where to start. any help would be appreciated!
Update: I now need help on number theory blue p15, p19 and p20. thanks!
So far, I have only finished 15.
Hint: Prime Factorize 2013 and remember 7!/6! = 7 (how can you use this for 2013 similarly?)
Hint for after you prime factorize: you must MINIMIZE a_0 + b_0. 61 is prime, 59 as well. How can you build an extra "60" term in the denominator?
